REPEATINGI-WATCH.

SPECIFICATION forming part of Letters Patent No. 402,343, dated April30, 1889.

Application filed September 12, 1888. Serial No. 285,182. (No model.)

To (LZZ whom, it may concern.-

Be it known that 1, CHARLES MORLET, of lloboken, in the county of Hudsonand State of New Jersey, have invented certain new and usefulImprovements in Repeatingatches, of which the following is aspecification.

This invention relates to an improved repeating attachmentto watches;and the object of my invention is to provide a simple, strong, anddurable motor for operating the repeating attachment.

A further object of my invention is to provide a simple moderating-gearwhich can be easily applied; and another object of my invention is toarrange and provide the entire repeating mechanism and itsmoderating-gear upon the face of the top plate in such a manher that noparts of the rotating mechanism extend to the bottom plate.

The invention consists in a repeating-watch having the moderating-gearmounted on an independent bridge on the top plate.

The invention further consists in a motor for the repeating-watchmechanism composed of a helical spring in the shape of a tube.

The invention also consists in the construction and combination of partsand details, as will be fully described hereinafter, and finally pointedout in the claims.

In the accompanying drawings, Figure l is a face view of my improvedrepeating mechanism for watches, parts being broken out and others insection. Fig. 2 is a side view showing the location and. arrangement ofthe motor. Fig. 3 is a side view of the bridge of the retarding-geanFig, .i is a face view oi. the repeating mechanism, the parts havingdifferent positions,

Similar letters of reference indicate corresponding parts.

The mechanism for transmitting motion from the repeaternnechanism motorto the hammers is of the old and wellknown construction, and does notform part of this in- 'vention.

A rod, A, which either a quadrant or a segment of a circle, is secured.at its ends in lugs a a, formed on the under side of the top plate, 13,or on any other plate of the watch. Said red A. is surrmiml ed by ahelical spring,

which two pins, d, project; or, in place of the pins (7, a fork isformed in any other suitable manner on said lug or the arm of the same.On the top of the top plate, 13, an angle-lever, E, is pivoted, which isprovided with an arm,

E, that passes between the pins cl on the arm D of the slide D. At theother end the lever E is provided with a segmental rack, F, engaging thepinion G, from which the curved ratchet-bars for operating the hammersin the usual manner are operated.

The pinion G engages the cog-wheel H, which is pivoted on the end of thelower shank of a U-shaped bridge, J, pivoted at its oppo' site end onthe upper surface of the top plate, B, by a screw or pivot, K, so as toadapt said bridge to oscillate, with the pivot or screw K as center, onupper surface of the top plate, 13. A spring, L, is secured at one endof the top plate, and the other end bears against the rim of theswinging bridge J, thereby keep ing the cog-wheel I l engaged with thepinion G. Between the shanks of said bridge J the wheels of themoderating-gear are mounted, which may be of any well-knownconstruction.

In the watch shown the wheel ll (ngages an intermediate cog-wheel, I,which in turn engages the pinion M, mounted on the same shaft with thecog-wheel. N, engaging the pinion 0 on the same shaft with the cog-wheelP, said cog-wheel Pengaging the pinion Q on the same shaft with theratchetavheel R,with which the escapement S engages. Said. es capeinentand the shaft on. which the pinions and cog wheels I M N O P Q R aremounted are all. pivoted in the bridge J.

The entire inoderating-gearbeing011 a sep arate bridge and entirelyindependent of the remaining repeating mechanism, it can be readilyremoved withoui disturbing or inter-- rupting the remaining parts of therepeating mechanism.

The operation is as follows: By moving the slide in the direction of thearrow 00', Fig. 1, the spring 0 is compressed and the rack F is moved inthe direction of the arrow x and rotates the pinion G in the directionof the arrow :0 The pinion G will not rotate the wheel H, but will pressor swing the entire bridge J and the Wheels thereon in the direction ofthe arrow Q34, so that the wheel H is out of the Way, and thus does notinterfere with rapidly compressing the spring 0 for action. WVhen theslide D has been moved as far as possible in the direction of the arrow00, the proper springs and catches provided are released and the partsof the repeating mechanism assume the positions shown in Fig. 4 readyfor striking. The slide D is now released, and the spring 0, expanding,moves said slide in the inverse direction of the arrow as, Whereby therack F is moved in the inverse direction of the arrow 00 and operatesthe striking mechanism in the usual manner. The pinion G is now rotatedin the inverse direction of the arrow :0 and turns the Wheel H in thesame direction in which the spring L acts. The result is that thepinionG now rotates the wheel H in the direction of the arrow w and from saidWheel H the moderating-gear is operated in the usual manner until thespring 0 has expanded and the slide D has been moved back to its initialposition. The helical-spring motor is much more durable, simpler, andstronger than a barrel or straight spring motor used heretofore and notso apt to get out of order.

The further advantage is that it occupies very little space, and that itis located in a part of the Watch and in space which is not otherwiseutilized, thus tending to reduce the size of the watch and case.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A repeating-watch having its moderating-gearmounted on a movable bridge, substantially as set forth.

2. A repeating-watch having its moderating-gear mounted on a bridgepivoted to 0scillate on a plate of the works, substantially as setforth.

3. A repeating-Watch having its moderating-gear mounted in a bridgepivoted at one end to oscillate on one of the plates of the works, thewheels at the opposite end of the bridge engaging one of the wheelsdriven by the motorof the repeating-gear,substantially as set forth.

4. In a repeating-watch, the combination, with the repeating-gear, of amoderating-gear mounted in an oscillating bridge on a plate of the worksand a spring acting on said bridge and serving to keep one of the wheelson the oscillating bridge engaged with one of the wheels operated by themotor of the repeating-gear, substantially as set forth.

5. A repeating-Watch having a motor for the repeating mechanism,composed of a helical spring surrounding a rod, substantially as setforth.

6. A repeating-watch having a motor for the repeating mechanism,composed of a helical spring surrounding a curved rod at the rim of themovement, substantially as set forth.

7. In a repeating-watch, the combination, with one of the plates, of acurved rod held at the rim of the same, a helical spring surroundingsaid rod, a slide on said rod, on which slide the spring can act, arocking lever operated from said slide, and gearing for transmittingmotion from said rocking lever to the repeating mechanism, substantiallyas set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

CHARLES MORLET.
